The crash, involving two tractor-trailers, happened in the northbound lanes near the Manada Hill/Hershey exit (PA 39).

PennDOT officials said the crash happened when one tractor-trailer sideswiped a tractor-trailer that had been parked along the road for the night. The tractor-trailer that caused the collision, flipped over and rolled into the trees along the road. The driver of that truck was killed, according to the coroner.

There is no word whether the driver in the other truck was hurt.

It's not uncommon for trucks to park along the road in that area. There is a wide shoulder and berm.
